Adjustment disorders

thumb|Homesick for Naples (1895), painting by Bertha Worms Homesickness is the distress caused by being away from home. Its cognitive hallmark is preoccupying thoughts of home and attachment objects. Sufferers typically report a combination of depressive and anxious symptoms, withdrawn behavior and difficulty focusing on topics unrelated to home. Experienced by children and adults, the affected person may be taking a short trip to a nearby place, such as summer camp, or they may be taking a long trip or have moved to a different country.
